More than 30,000 Simpsons fans submitted entries. But only one fan was chosen as the winner of The Simpsons couch gag contest.

In this exclusive behind-the-scenes video, TVGuide.com can reveal that Cheryl Brown's "Dandelions" was the winning entry and will appear in Sunday's season finale (8/7c on Fox). "Over the years, people have suggested many couch gags and we thought, you know, let's turn this into a contest. Let's make this pay off!" series creator Matt Groening says.
